摘要： A spindle motor includes a spindle motor hub that supports one or more disks, and has a contact area reduction portion that minimizes the area of contact between the hub and a disk when the disk is mounted to the hub. The spindle motor hub includes a hub body having a cylindrical sidewall that includes a contact section around which the disk extends and a non-contact section. The non-contact section is constituted by the contact area reduction portion. An outer diameter of the cylindrical hub body at the contact section is greater than an outer diameter of the cylindrical hub body at the contact area reduction portion of the non-contact section.

摘要： Provided is a spindle motor for a hard disk drive (HDD). The spindle motor includes a shaft, a stator and a rotator coupled to an outer circumference of the shaft, and a height adjustment member detachably installed on the rotator and adjusting the height of the rotator when the number of data storage disks mounted on the spindle motor is changed. The spindle motor further includes a plurality of spacers mounted around outer circumferences of the height adjustment member and the rotator in order to maintain a distance between adjacent disks, a clamp disposed over the height adjustment member and fixing the disks and the spacers, and a clamping screw coupled to an upper end portion of the spindle motor and fixing the height adjustment member and the clamp. Accordingly, since the height of the rotator can be adjusted using the height adjustment member, the number of disks mounted on the rotator can be changed.

摘要： An HDD includes a head stack assembly, a voice coil motor, and a retracting pin unit. The retracting pin unit includes a mobile retracting pin generating a retracting force to maintain the actuator arm at a predetermined position by interacting with the magnet when the read/write head is parked, and coupled to the bobbin to be capable of relatively moving with respect to the bobbin toward the magnet when the bobbin is separated from the magnet due to an external shock. A head on disk phenomenon, in which the parking state of the read/write head is removed when an external shock such as a linear shock or a rotary shock, which may be generated as the HDD is installed in a notebook computer, is applied to the HDD, may be reduced.

摘要： A method and apparatus for controlling a rotation of a motor in a disk drive. The method includes: performing spin-up when the disk drive is operating and determining whether a disk rotation speed is less than predetermined target constant revolutions per minute (RPM); rotating a disk at predetermined low RPM when determining that the disk drive is at a low temperature and changing a rotation mode to a low-speed rotation mode if it is determined that the disk rotation speed is less than the predetermined target constant RPM; and spinning up the disk to the target constant RPM when determining that the temperature of the disk drive has increased and changing the rotation mode to a high-speed rotation mode if a disk rotation driving current decreases below a predetermined reference current value while the disk is rotating at the low RPM. Accordingly, since spin-up can be normally performed through a step-by-step spin-up process even if a disk drive operates at a very low temperature, a normal operation and reliability of the disk drive can be guaranteed, and an excessive driving current for the normal operation of the disk drive is not required at the very low temperature.
摘要翻译：一种用于控制磁盘驱动器中的电动机的旋转的方法和装置。该方法包括：当磁盘驱动器正在运行时确定磁盘旋转速度是否小于预定的目标转数/ RPM（RPM）; 如果确定盘旋转速度小于预定目标常数RPM，则当确定磁盘驱动器处于低温并且将旋转模式改变为低速旋转模式时，以预定的低RPM旋转磁盘; 并且当确定盘驱动器的温度升高并且当盘旋转驱动电流降低到低于预定参考电流值时将盘旋转模式改变为高速旋转模式，并将盘旋转到目标恒定RPM 以低RPM旋转。因此，即使磁盘驱动器在非常低的温度下操作，通常也可以通过逐步旋转加工来进行自旋起动，可以保证磁盘驱动器的正常运行和可靠性，并且过度驱动在非常低的温度下不需要磁盘驱动器正常运行的电流。

摘要： In a hard disk drive, at least one groove is formed in any of the base plate and the cover plate to pump air toward an outer side of the disk. An outer end of the groove is located at a position inwardly separated from an edge of the disk such that an air journal zone of predetermined width is formed along a circumferential direction of the disk between the outer end of the groove and the edge of the disk. The groove is formed in multiple numbers in a circumferential direction of the disk at a predetermined interval and is extended in a radial direction from an inner side of the disk and curved in a direction in which the disk rotates. Thus, vibration of the disk is reduced by a damping operation of air pumped by the groove having a high pressure in the air journal zone.
